Thanks for the presentation!
I wanted to buy a YSP-2500 last year, but realized that my room configuration would make it a poor choice (full window on one side, stairs and corridor on the other side) and I'm looking at alternatives for that. Saw the E5/12 which could have been a good choice, and now I'm eager to hear your test on the E6 that is coming soon.
Two option for me: either the E6 or maybe using a YSP-2700 or YAS306 with two X10 on the rear.
I'll just wait and see what you guys think of both ;-)
